I love Tatum, but he isn't Dirk (at least not yet).
True.
All the same, Tatum showed this year that he can play like a super duper star for stretches:
30.7 pts, 7.9 reb, 3.2 ast on 63.7% TS in February (12 games)
In the playoffs against Philly:
27 pts, 9.8 reb, 2.5 ast, 2.3 blks on 60.7% TS (4 games)
In the playoffs against Toronto:
24.3 pts, 10.3 reb, 5.3 ast, 1.0 stl on 55.3% TS (7 games)
He struggled a bit, arguably, against Miami, but still put up:
26.5 pts, 9.8 reb, 6.3 ast, 1.3 stl, 1.2 blk on 54.7% TS (6 games)
Here is where we put the obligatory "He's only 22 years old!"
He's already very, very, very good. It's reasonable to expect him to improve -- indeed, it would be
unreasonable to expect that he won't improve.
In particular I think he has a lot of room to grow as a closer. He showed he could carry the team for stretches this year; the next step is to show that he can take over a game and put an opponent away in the fourth quarter whenever the team needs him to do it, not just sometimes.
